What better place to celebrate a holiday like National Margarita Day than singer-songwriter and island-lifestyle enthusiast Jimmy Buffett’s Margaritaville at Universal CityWalk?

The kick-back, tropical-themed restaurant and bar is celebrating its official one year anniversary on National Margarita Day and to mark the occasion, it’s rolling out the new margarita flights ($19). The flights include the more traditional Who’s to Blame Margarita, the sweeter Fins to the Left, which is made with Blue Curacao, the refreshing Watermelon Margarita with fresh watermelon wedge garnish and the Last Mango in Paris, a delish drink with a pop of Cointreau Orange Liqueur.

On Thursday, Liz Garriott, general manager of Margaritaville at Universal CityWalk, said the staff is prepared to serve up a lot of margaritas in observance of this important national holiday.

One of her favorite drinks is the not-on-the-menu Cadillac Margarita ($14), which she said the staff just recently perfected.

The secret to the margaritas served up at Margaritaville is the housemade sour mix, Garriott said.

“Our sour mix is our pièce de résistance,” Garriott added. “We have worked very, very hard on this to make sure it’s absolutely perfect. I’ve spent a lot of time trying margaritas, doing what I’ve had to do to test them and make sure they’re perfect and this housemade sour mix, I can tell you the exact dimensions, but I’d have to kill you. However, it is fresh squeezed lime juice, fresh squeezed lemon juice, our house simple syrup and a splash of orange juice and it is made every day by our chef in-house and it makes all the difference.”

The most popular margarita sold at Margaritaville is the Who’s to Blame ($10.50), which was created by Buffett himself. The second most popular, Garriott said, is the Perfect Margarita ($11.75) which uses Margaritaville gold and silver tequilas, triple sec, Orange Curacao and lime juice.

“It’s really the margarita for the margarita aficionados,” Garriott said.

As far as food pairings, Garriott suggests the Perfect Margarita with the Lava Lava Shrimp ($13.25) or the Salmon Salad ($14.95). Grab a Cheeseburger in Paradise ($14.45) entree or share the Volcano Nachos ($16.95) when you pick up a Who’s To Blame Margarita.

Margaritaville is open until 11 p.m. on National Margarita Day and Happy Hour is from 3-6 p.m. and that includes the Who’s to Blame and Tropical Fruit Margaritas for $6.
